The Apeks Flight Stage 4 Set is built to be the lightest complete regulator set possible complete with Flight regulator, Flight Octopus, and double gauge. Released in 2009 and is still the lightest regulator in the world designed for travelling divers in waters down to 10°C. The double gauge includes a combined contents (pressure) gauge and depth gauge with a luminescent dial for easy reading. This gauge has metric measurements and can be used up to 360 bar and down to 70 metres. All components of the Flight Stage 4 set work seamlessly together.

Apeks Flight Stage 4 Set - Pewter - Features

?This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air.

No

Adjustable Venturi

?The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing.

Yes

Cold Water Rated

?Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.

Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.

EN250 / (EN250A >10°C)To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C.

Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming.

No

First Stage

?Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.

Balanced regulators are not affected by the cylinder pressure or depth.

Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers.

?All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.

Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run.

Really, Really Good

I travel quite a bit, and as well as that, all my diving is at the end of a flight, so all my gear is orientated towards flying.

This regulator set is really great, it's very light but robust.

The second stage is very easy to wear in the water, it's light so you don't feel the need to clamp down so tight on the mouthpiece and it has a very comfortable draw when breathing.

I bought this as a set and added a BCD hose to it.

My only real bug-bear with it is that I would have liked the option to add a console with a compass rather than the two-dial console that came with it. I asked and was told that the two dial option was the only one available. A three dial console would have, for me, made this an 11 out of 10 piece of kit.

The best

Not much to say really, parks regs too if there game, light weight, easy to use, great holiday regs which use top quality materials to provide an amazing product.

Only criticism the octopus hose could do with being a slightly larger size as well as the gauge hose (personally felt they were a bit shorter than required.

I''ve had my Flight set for two years and now have a good sense of its capabilities. For UK diving I use an Oceanic Alpha 9 rig and, hand on heart, I prefer the breathability and performance of the cheaper regulator. The trouble is, it''s heavy which
